GUEST: My mother-in-law made these shadow boxes for each of her four sons after their father passed away.

They each contained different medals and photos that she had reproduced in there.

APPRAISER: Who is this individual to you?

GUEST: Uh, Jacob Beser is my father-in-law.

APPRAISER: Tell me about what he did in World War II.

GUEST: He was the, uh, radar countermeasure.

He controlled whether or not the bomb would detonate in air.

He did both missions in Hiroshima and Nagasaki.

APPRAISER: That's got to be a fairly rare thing.

GUEST: It is-- he was the only man that did both missions.

He, um, considered it his job to the United States.

He joined right after the bombing of Pearl Harbor.

And his whole speech was that he would hope that this would never happen again.

He is, um, the only Jewish man in Baltimore that participated in the bombing, so, he was very concerned about what was going on during World War II.

APPRAISER: You've got her copy of the photograph, because we saw the original in the material.

We've got the newspaper bit for context.

And then down here, his miniature medals: the Silver Star, the Distinguished Flying Cross, the Air Medal, American Campaign, Asiatic-Pacific, and the World War II Victory.

But the real stars of the show are these two pieces here at the very bottom, this little leather band and I.D.

bracelet and, more so, the identification tag.

And the reason why those have more significance than the medals is because those would have been on his person when he flew those missions.

To put a value on this could be perceived as disrespectful.

It is not intended in that way.

It simply reflects the position of the item within the demand for extremely historical military memorabilia.

We discussed it at the table amongst our colleagues and believe that a conservative auction estimate for this, just what you see here, would be between $3,000 and $5,000.

GUEST: Wow.

That's amazing.

Well, it'll always be with the family.

APPRAISER: This is really a window into a pivotal moment in world history.
